SPECIFICATION forming part of Letters Patent No. 380,285, dated March 2'7, 1888.

Application filed September 2?, 1887. Serial No. 250,869. (No model.)

To aZZ whom it may concern:

Be it known that I, EUGENE A. HOYT, a resident of Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Cultivators;

and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in cultivators, and is to control the relative working depth of the shovels on the two beams of the sulky corn-cultivator separately from the drivers seat, either while traveling or stopping, by raising and lowering the forward ends of the beam separately by means of lever attachments worked in harmony with the levers employed to adjust the'rear ends of the beams, and is fully described and explained in this specification, and shown in the accompanying drawings, in which Figure 1 is aside elevation of my improved cultivator. Fig. 2 is a vertical section of one of the vertical standards D, dependent from the main frame of the cultivator. Figs. 3 and 4 are detail views illustrating the attachment to said standard of the adjustable bracket supporting the front end of the cultivatorbeam. Fig. 5 is a plan of one side of the cultivor, and Fig. 6 is a plan of a portion of one of the locking-levers G, and the locking device attached thcreto, the segment I, with which said looking device en gages,bei ng shown in section.

In the views, A is one of two symmetricallyplaced beams joined at the forward end, serving as the pole, which are connected by a crossbar, A, and forming therewith the main frame of the cultivator. The rear ends of the beams A rest upon and are fastened to a transverse axle, C, on whose ends are mounted wheels B, of any ordinary construction, which support the cultivator-frame. Beneath each of the ends of the crossbar A and rigidly fastened thereto is a tubular vertical standard, D, held in place by an axial rod, (1, and braced by an oblique rod, d, whose upper end is fastened to the corresponding beam A at a point in front of the standard.

The details of construction and attachment of each of the standards D to the frame of the cultivator may be modified in various ways; but I prefer that form shown in the drawings, and particularly in Fig. 2, in which (1 is a casting resting upon the upper surface of the crossbar A and provided with vertical ears, whose use will be hereinafter explained.

d is a cap lying below the end of the crossbar and receiving the upper end of the tubular standard, and d is a similar cap covering the lower end of the standard. The rod d is provided with a head at its upper end and extends downward through the casting d, the crossbar A, the caps d 61, the standard D, and the end of the brace cl, and is secured by means of a not engaging its screw-threaded lower end.

Upon the standard D slides freely up and down a bracket, E, whose front end is provided with a series of suitably-journaled antifriction rollers, r r, lying on opposite sides of thestandard and permitting the free vertical adjustment of the bracket at the same time that they hold it firmly in a horizontal position at any point where it may be placed. The bracket is supported and adjusted by means of a rod, g, whose lower end is fastened to the bracket, while its upper end is fastened near the front end of a lever, G, which is pivoted near its center to the upper end of a standard, H, fastened to the frame of the cultivator. A toothed segment, I, is pivoted between the ears of the casting d, already referred to, and extends upward therefrom, passing through a guard, i, fastened to the front end of the lever G. A latch, 'i, engages the toothed segment and is operated by means of a rod, i, and a spring, 8, in the manner common in looking devices of this class.

It is evident that the depression of the rear end of the lever G raises the front thereof and moves the bracket E and the front end of the beam upward, and that a reverse movement of the lever moves the bracket and the front end of the beam downward, and thelever may be secured in any desired position by the engagement of the latch t and the segment I.

To the rear end of the bracket E is pivoted the front end of a cultivator-beam, F, provided with plows 0r shovels f of any desired construction. The rear end of the beam F is supported and may be vertically adjusted by means of a chain, g, passing upward and over a pulley at the upper end of the standard I, fastened to the frame of the machine, the front end of the chain being fastened to a lever, G, whose front end is pivoted to a standard, H, fastened to the frame of the cultivator. The standard I is perforated or toothed, and the lever G is provided with a locking device of any desired construction adapted to engage the perforations or notches in the standard I; and it is evident that if the rear end of the lever G be depressed the rear end of the cultivator-beam will be raised, and that a reverse movement of the lever will lower the rear end of the cultivator-beam.

By means of the two levers G G and their connections with the cultivator-beam the ends of the beam may be separately or simultaneouslyraiscd or lowered, and any desired independent vertical adjustment of either end of the beam may thus be secured, and at the same time the connection of the cultivatorbeam through the bracket E with the standard D is such as to permit free lateral movement of the beam. The levers G G are so placed that they may be easily and conveniently operated by the driver, either when walking or from the drivers seat, where the devices are attached to a ridingcultivator, and at the same time the connection of the cultivatorbeam with the cultivator-frame, by means of the bracket E, is such as to hold the cultiv-ator-beam securely in any given position in which it may be placed by the operator.

So far as I am aware, it is new to provide the cultivator-beam of a wheeled cultivator.

thevertical standard D, dependent therefrom, 4

and the bracket E, vertically adjustable on said standard, of the pivoted lever G, supported by the frame of the machine, the guard 'i, fastened to said lever, the latch 11, operating-rod i, and spring 3, the toothed segment I, pivoted to the frame of the machine and passing through the guard i, and the rod 9, connecting said lever G with the bracket E, substantially as shown and described, and for the purpose set forth.

2. The cultivatorframe with the levers G G, the hollow standards or hangers D, secured to the frame by the bolt (1", and thepivoted rack l, in combination with the sliding bracket E, having rollers 1' r, the plow-bea|i1 pivoted thereto, and the lever-connections g g, substantially as shown and described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

EUGENE A. HOYT.
